| Abstract: | The whole and fresh Houttuynia cordata was collected,then dried in low temperature,after that extracted by supercritical CO2 extraction.Orthogonal test design was used and the effect of the pressure,temperature,CO2 flowing rate to the extraction rate of the Volatile Oils from Houttuynia cordata with supercritical CO2 extraction were reached.The results showed that the optimal extracting conditions were the pressure 30 MPa,the temperature 45 ℃,the CO2 flowing rate 20 kg/h. |
